Sparsistency of -Regularized -Estimators
Yen-Huan Li, Jonathan Scarlett, Pradeep Ravikumar +1
We consider the model selection consistency or sparsistency of a broad set of -regularized -estimators for linear and non-linear statistical models in a unified fashion.…
Second-Order Asymptotics for the Discrete Memoryless MAC with Degraded Message Sets
Jonathan Scarlett, Vincent Y. F. Tan
This paper studies the second-order asymptotics of the discrete memoryless multiple-access channel with degraded message sets. For a fixed average error probability and…
The Saddlepoint Approximation: Unified Random Coding Asymptotics for Fixed and Varying Rates
Jonathan Scarlett, Alfonso Martinez, Albert Guillén i Fàbregas
This paper presents a saddlepoint approximation of the random-coding union bound of Polyanskiy et al. for i.i.d. random coding over discrete memoryless channels. The approximation…
